Rear Panel Features

(AMIS60 shown. The AMIS120 has identical rear panel features)

230V/240V Slide Switch

The operating voltage of the amplifier is user selectable between 230V and 240V via a slide switch located
on the top left side of the rear panel. This switch should be set to match the AC voltage of your country.

AC Power Inlet

The 3 pin IEC power inlet is located on the bottom left of the rear panel and accepts a standard mains
power lead fitted with an IEC connector. Before plugging in a power lead, please check the rear panel of
the amplifier to ensure that the voltage switch is set correctly for your part of the world.

The operating voltage is 230/240 VAC @ 50 Hz or 115 VAC @ 60 Hz with factory modification. The inlet
is equipped with an inbuilt AC fuse holder fitted with a 4 amp fuse (ACM120) or a 2 amp fuse (ACM60)
plus a spare within the holder.  Power  consumption is 125 watts  for the AMIS60 and 250 watts the
AMIS120.

 ---- Please ensure that the mains power cord is disconnected before attempting to check or replace
this fuse----

24 Volt DC Power Inlet

The AMIS60 & AMIS120 feature optional 24VDC power to run off a battery supply if required. This is
connected via the rear terminal strip. The front panel Power Switch will not switch DC power ‘on’ or ‘off’
in DC operation. In this mode the amplifier is always ‘on’.

Speaker Output Terminal Strip

The screw terminals on the left hand side of the strip allow access to

 

the direct speaker outputs of the

amplifier. The screw terminals on the right hand side are for activation of the in-built 4 tone generator.
Reading from left to right the terminals are:

COM

Common or “-” for low impedance speaker loads (4 or 8 ohms).

4

Positive “+” for 4 ohm speaker loads (use with common) (AMIS120 only)

8

Positive “+” for 8 ohm speaker loads (use with common)

COM

Common or “-” for 70v or100v speaker loads (maximum load of 80 ohms at 100v 

AMIS120 & 160 Ohms at 100v AMIS60)

25

Positive “+” for 70v line speaker loads (use with common)

70

Positive “+” for 100v line speaker loads (use with common)

Please ensure that the correct “Common” is used. Low impedance and 70/100v loads can be used
simultaneously but please pay careful attention to the overall speaker load. When used individually, the low
